How can I merge objects in Sverchok and Animation Nodes?
Yes it's possible. First we need to put all objects inside a collection.

Using Animation Nodes

In Animation nodes we can use collection info node to get all objects, then convert them into mesh list using Mesh Input node(Mesh Input node don't have vectorized input so we need loop). finally merge it using Join Mesh List node.


Using Sverchok

In sverchok we only need these 3 nodes, Our new connected object is Alpha.0000
